glibc2 defines struct dirent differently than the Linux kernel does.
The getdents function therefore needs to read a heuristically defined
number of kernel dirents to satisfy the request. In case where too
many kernel dirents have been read, the function lseeks on the
directory so that a next call will start with the right dirent. The
offset used in lseeking is the offset-field in the last dirent passed
to the application. This can only mean that the offset-field holds
the offset of the next dirent and not the offset of the dirent itself.

and if_ar drivers, and PPPOE support soon. See:

to remove 'b'lock devices. The agreement is, essentially, that
block devices will be collapsed into character devices as a first
step (though I don't particularly agree), and raw device names 'rxxx'
will become simply 'xxx' in devfs in the second step (i.e. no 'rxxx'
names will exist). The renaming will not effect the original /dev
and the expectation is that devfs will eventually (but not immediately)
become the standard way to access devices in the system.
If it is determined that a reimplementation of block device access
characteristics is beneficial, a number of alternatives will
be possible that do not involve resurrecting the 'b'lock device class.
For example, an ioctl() that might be made on an open character device
descriptor or a generic buffered overlay device.
This commit removes the blockdev disablement sysctl which does not
apply to the solution that was reached.
and unusable by the pccard system since pccard doesn't attach to the

0 is used directly for resource allocation and this fails when unit 0
isn't actually attached to anything.

it has the same value on all platforms. Previously it was just under
3 seconds on x86 (typically hz<=128) and just under 1/3 of a second on
alpha (typically hz>=1024). This covers up a race between ad_interrupt()
and ad_timeout() which is being looked into.

This means that access to block devices nodes will act the
same as char device nodes for disk-like devices.
If you encounter problems after this, where programs accessing
disks directly fail to operate, please use the following command
to revert to previous behaviour:
sysctl -w vfs.bdev_buffered=1
And verify that this was indeed the cause of your trouble.

bootup. Somehow my backout of an abortaive attempt at shared
memory autoconfiguration included this line:
sc->mem_shared = 1;
Which is fairly important as it turns out.
Since I performed my pre-commit testing on a different box with a generic
NE2000 I didn't catch this. Pointy hat.

upon isp->isp_maxcmds. Allow for multiple calls to mbxdmasetup (for
isp_reset cases).
file later. Do some pencil-sharpening types of minor changes. Change
how active commands are remembered (using new inline functions to get
handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as
outgoing mailbox 2 will tell you the f/w's notion of the max commands
that can be supported. Attempt to retrieve loop topology. Add in the
appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little
Endian machines but is needed for sparc (on other platforms)). Move
the temp port database we use to find out where things have moved to
after a LIP to the softc and off the kernel stack. Follow Qlogic's
hint and don't bother setting a tag for commands that don't have
this enabled (presumably the f/w will do it's own selection then).
Use an INT_PENDING macro to check for an interrupt. The call to
ISP_DMAFREE now just takes the handle- not the 'handle-1' which was
a layering violation. Use CFGPRINTF in a couple of places to make
things less chatty if not booting verbose, or CAMDEBUG compiles, etc..
where it defaults to one. Change simq width allocation to the max number
of commands supported by the HBA after f/w fires up- not the constant
MAXISPREQUEST value. Do some stylistic changes.
